For example, The Navy built a solar array across it’s parking lot at the cost of 1.9 million dollars (all Stimulus money). It’ll only save 30,000 dollars a year for them. Which means it will pay for it self after 63.3333 years (assuming they don’t spend those savings). If for instance they put the saved money in the bank to collect with interest. So say the payback could be under 40 years or so. But as for the panels, they’ll be obsolete in about 10 years. And removed after 15-20, Now you have to contract, pay and install new more modern ones and pay for the safe disposal of the old panels, as these high efficiency solar cells are made of gallium arsenide (arsenic compounds for all those who failed chemistry class) and germanium, not silicon. Don’t forget the cost of maintenance, cleaning and service. Where’s the cost saving. All it will do is generate only a fraction of the power needed to run the base. It’ll look good when politicians stand there to cut the ribbon. If GM wanted to save money why not buy a tri-generator. It generates electricity, heat (water), and air conditioning in one. Instead they spent stimulus money too on an otherwise useless solar device, instead why not focus on building and selling cars and paying back your debts.
